Abstract

This work outlines system and usage principles of the ontology-based
information extraction system iDocument. Ontology-based information extraction
reuses existing domain knowledge for extracting and annotating relevant
information from domain-related text. iDocument provides an architecture, an API,
and a user interface for supporting users and developers in ontology based
knowledge annotation and acquisition tasks. The main contribution of this work is
a generic and standardized information extraction template interface for retrieving
relevant information from text by using existing domain ontologies.
